H2S is involved in ABA-mediated stomatal movement through MPK4 to alleviate drought stress in Arabidopsis thaliana

Aim Hydrogen sulfide (H2S) is a gaseous signaling molecule that participates in multiple physiological processes in both animals and plants. Mitogen-activated protein kinase (MAPK) is important signaling molecule that links the growth and developmental signals and environment stimuli to cellular responses. In the current study we explored the relationship between H2S and MAPK in drought stress resistance in Arabidopsis.
